CHANNEL FOR FIRE-SI-IUTTERS.

Specification of Letters Patent.

Patented July 28, 1914.

Application filed October 28, 1912. Serial No. 728,031.

To all whom it may concern Be it known that I, EDVJARD H. MoCLoUn, a citizen of the United States, residing at Columbus in the county of Franklin and State of (lhio, have invented a certain new and useful Improvement in Channels for Fire-Shutters, of which the following is a specification.- I p The principal object of this invention is to provide improved means for holding a metallic channel guide or other member for a fire shutter, curtain or the like so that it may expand when subjected to the heat of fireand be maintained in straight condition so as to permit the proper operation of the shutter or curtain.

The invention is embodied in the example herein shown and described and then pointed out in the claims.

in the accompanying drawingsFigure 1 is a plan view of the upper end of a channel or guide according to my invention. Fig.2

IS a vertical elevation. of the channel or guide on a smaller scale.

In the views the channel or guide 3, which is of metal, is shown in the form of a tube longitudinally open at one side, as shown at 3% to admit the edge of the shutter or curtain. In practice two of such channels are usually employed, one at each of the opposite sides of the opening that is closed by the shutter or curtain. The channel is held in proper position on the wall of the building or other structure by means of cast metal bifurcate brackets 4 embracing the channels at suitable short intervals along the length of the channel. he brackets l have shanks t throughwhich bolts 5 are passed into the wall, shown at 6 Fig. 1, or into the nuts of ordinary expansion shells inserted into the wall, as indicated at 7 l3 1. The channel is secured in position in the brackets at one point only by means of a set-sore v 8. In the drawing the set screw 8 is shown in the uppermost bracket, but it can be secured in any of the brackets.

When the channel, secured as shown, issubjected to the heat of fire it expands principally downward, the brackets not obstructing such expansion. Ttis obvious that if the channel were secured atv its lower end, instead of at its upper end, the channel, when subjected to the, heat of lire would expand upward. If the channel were secured, in an intermediate bracket it would be capa ble ofexpanding in both directions. The brackets 41 should not embrace or inclosethe channel so closely as to interfere with the w free and proper expansion of the channel, but it is advisable to have them in such proximity to the channel-as will prevent undue warping or buckling of the channel when subject to the heat of tire. The shapes of the parts can be modified without departing from the gist. of the invention.

lVhat I claim is:

1. The combination with a channel orthe like member that is subject to expansion by heat, of means for holding the same consisting of a plurality of stationary brackets disconnected with but closely surrounding said member, said brackets being suitably spaced to prevent buckling, and means in one of said brackets to hold said member for expansion with reference to another of said brackets.

2. In combination with a channel or the like member that is subject to expansion by heat, of means for holding the same consisting of a plurality of brackets disconnected with but closely surrounding said member suit-ably spaced to prevent buckling of the member, and means to hold said member at one point to permit expansion of said member with reference to said brackets when the member is subjected to the adequate heat of fire.
